Popular Electronics Winter 1969 Electronic Experimenters Handbook
This is an original 156 page, 6 1/2” x 9 1/8”, Winter, 1969 Popular Electronics Electronic Experimenter’s Handbook. The handbook was copyrighted and published in 1968 by Ziff-Davis Publishing Company.
Contents – Contents of the more comprehensive and significant are in the first three chapters covering the first 135 pages of the handbook. The fourth chapter includes several short articles and the final two page chapter includes only obsolete marketplace ads. Chapter titles and articles from the first four chapters are:
Useful Projects – Universal Strobe Goes Psychedelic (The ‘Universal Strobe” described in this article will not only be the hit at your next party, but can also earn its keep by performing other, less glamorous duties) ; Motor Speed Control (Variable Speed at Full Torque) ; Build Your Own Memo Minder (Urgent Notes and Telephone Messages Make Themselves Known) ; Build a Stopclock (Electronic timer turns on or off at any preset interval from one second to ten minutes) ; Build Simple-Minded “Maggie” (An electric motor with a warped coil-less armature) ; Modern Slot-Car Controller (Any speed at maximum torque with electronic braking as a bonus) ; Build a Stacked-Antenna AM Radio (Two antennas can be better than one).
Audio Stereo Hi-Fi Projects – Build L’il Tiger Stereo Power Amplifier (New transistor design has 22 watt music power capability) ; For That Different Sound… Music A La Theremin (The first true all-electrical musical instrument–brought up to date using bipolar transistors and FET’s) ; Add “Comply” to Your Tape Recorder (Distortionless speech compressor is invaluable aid) ; Reverb-b-b Adaptor (How would you like to incorporate a controllable echo in your audio system?) ; Build a FET Mixer (Low-cost FETs make perfect 3-channel mixer) ; Mighty-Mag Speaker System (Build your own ultra-compact Hi-Fi speaker enclosure) ; Instant Non-Fat Speaker Enclosure (Test speaker finds a new home) ; The Electronic Technician Shortage (Straight-from-the-shoulder discussion of how to be hired, how to stay employed, and who doesn’t get anywhere).
Lab & Test Equipment Projects – Low-Cost Counting Unit (You can assemble true digital readout at per decade) ; Build an IC ‘Testone’ (Utility square-wave generator features high output and low cost) ; Build Ultra-Fast Electronic Stopwatch (Using the low-cost decimal counting units) ; Build the MGW Transistor Tester (Stop wondering- the “no-guesswork” tester checks for silicon-germanium and NPN or PNP ; Experimenter’s Short-Proof power Supply (build 2-ampere, 0.32 volt power source for your bench) ; Low-Cost High-Quality Electronic Voltmeter (Almost non-loading voltmeter measures from 0.5 to 150 volts full scale, and is ideal for testing semiconductor circuits) ; Versatile Regulated Low Voltage Power Supply (for your workbench) ; Build FET Crystal Calibrator (Combination of FET and drift-field transistor will produce 100-kHz harmonics) ; Police Special II (Some of the most fascinating radio activity you will ever hear takes place 24 hours as day in the band of frequencies lying between 152 and 176 MHz) ; The “Ferret” Drags Them In (Single-control preselector peps up short-wave reception).
The Best of Tips and Techniques – As stated above, this chapter includes brief articles. Article titles are – Make-It-Yourself Phone Jack From Scrap Parts ; paper-Clip Jig Holds Printed Circuit Board ; Model Airplane Cement Reduces Corrosion and Shock Hazard ; Use Permanent Marker Pen to Lay Out Etch Pattern ; Cancel Mono Noise on Stereo Records ; Plug-In Dust Cover Makes Modifications Safe and Easy ; Cable Connectors Save Time and Effort ; Hidden Switch Prevents Unauthorized Use of Electronic Devices ; Stripped Screw Holes Can be Beefed Up by “Staking” ; Old Trick Keeps Tape from Unwinding ; Plug-In Loop Adapter for Clamp-On Ammeters ; Select–Don’t Settle–from Two Filament Transformers ; Electric Food Mixer Doubles as Light-Duty Drill ; Fuse Holder Doubles as Phone Jack ; Use Two Isolation Transformers to Eliminate Shock Hazard ; Telescoping Antenna Doubles as Multiple Coil Form ; Bolt Speakers Together to Prevent Cone Damage ; Salvaged Tube Pins Adapt Crystals and Coils to Tube Sockets ; Fuse Both Sides of the A.C. Power Line ; Cable Shield Speeds and Simplifies Desoldering ; Simple Jig Improves Appearance of Projects ; Make Your Own Miniature Mercury Switch ; Color-Coding Save Time when You’re Looking for a Specific Tool ; Flashlight Cells Protected and Dated ; Mechanical Drafting Pencil Lends a Third Hand ; Color Indicator Lamps and Lenses with Modelers Paint.
